6.1.5 The levelling system operating buttons
A few buttons are sufficient to operate the basic control functions.
Up button & down button
In automatic mode, the up button and the down button are used to change the
nominal control value.
In manual mode, the corresponding valve output is actuated during the time in
which the relevant button is pressed.
In the menus, these serve to select menu items or to set parameters.
Enter button
The enter button is used to set the nominal value to the actual value and/or to
carry out calibration to zero.
In the menus, it serves to confirm the relevant menu item which has been
selected.
Auto button
The auto/manual button serves to switch between manual and automatic
operating modes.
Manual mode
In "manual" operating mode, the screed is moved directly using the up/down
buttons on the remote control.
The function LED integrated into the button is off in manual mode.
Automatic
In "automatic " operating mode, the screed's nominal value is changed using
the up/down buttons on the remote control.
If comparison of the measured actual value and the set nominal value results in
a difference, the remote control independently actuates the outputs with the aid
of the higher-level control system until this difference has been compensated.
The function LED integrated into the button lights up in auto mode.
